What would you want to come home to?

My parents are gone for a few days visiting my new niece for her first birthday, but I am home here taking care of their house. I normally go to the supermarket to stock up for them (juice, milk, bread, etc.), but this time they are already stocked, since they are only away for a few days.

However, the flights and layovers, etc., all add up to a long day of travel and I want to make them something to have in their fridge (to reheat) that they can just pull out, throw in the oven/microwave, and enjoy after a long trip home.

If you were my parents, what would you want to come home to? Lasagna? Pizza? Casserole? I am open to all ideas!
